  :::

  In WarpDrive a Serializer is used to serialize and deserialize
  records when they are transferred in and out of an external source.
  This process involves normalizing property names, transforming
  attribute values and serializing relationships.

  `JSONAPISerializer` supports the http://jsonapi.org/ spec, though
  even compliant {json:api} servers may find writing an application
  specific serializer better suited to their needs and more performant.

  This serializer normalizes a JSON API payload that looks like:

  ```js [app/models/player.js]
  import Model, { attr, belongsTo } from '@warp-drive/legacy/model';

  export default class Player extends Model {
    @attr('string') name;
    @attr('string') skill;
    @attr('number') gamesPlayed;
    @belongsTo('club') club;
  }
  ```

  ```js [app/models/club.js]
  import Model, { attr, hasMany } from '@warp-drive/legacy/model';

  export default class Club extends Model {
    @attr('string') name;
    @attr('string') location;
    @hasMany('player') players;
  }
  ```

  ```js
    {
      "data": [
        {
          "attributes": {
            "name": "Benfica",
            "location": "Portugal"
          },
          "id": "1",
          "relationships": {
            "players": {
              "data": [
                {
                  "id": "3",
                  "type": "players"
                }
              ]
            }
          },
          "type": "clubs"
        }
      ],
      "included": [
        {
          "attributes": {
            "name": "Eusebio Silva Ferreira",
            "skill": "Rocket shot",
            "games-played": 431
          },
          "id": "3",
          "relationships": {
            "club": {
              "data": {
                "id": "1",
                "type": "clubs"
              }
            }
          },
          "type": "players"
        }
      ]
    }
  ```

  to the format that the JSONAPICache expects.

  ### Customizing meta

  Since a JSON API Document can have meta defined in multiple locations you can
  use the specific serializer hooks if you need to customize the meta.

  One scenario would be to camelCase the meta keys of your payload. The example
  below shows how this could be done using `normalizeArrayResponse` and
  `extractRelationship`.

  ```js [app/serializers/application.js]
  import JSONAPISerializer from '@warp-drive/legacy/serializer/json-api';

  export default class ApplicationSerializer extends JSONAPISerializer {
    normalizeArrayResponse(store, primaryModelClass, payload, id, requestType) {
      let normalizedDocument = super.normalizeArrayResponse(...arguments);

      // Customize document meta
      normalizedDocument.meta = camelCaseKeys(normalizedDocument.meta);

      return normalizedDocument;
    }

    extractRelationship(relationshipHash) {
      let normalizedRelationship = super.extractRelationship(...arguments);

      // Customize relationship meta
      normalizedRelationship.meta = camelCaseKeys(normalizedRelationship.meta);

      return normalizedRelationship;
    }
  }
  ```

    ```js [app/models/comment.js]
    import Model, { attr, belongsTo } from '@warp-drive/legacy/model';

    export default class CommentModel extends Model {
      @attr title;
      @attr body;

      @belongsTo('user', { async: false, inverse: null })
      author;
    }
    ```

    The default serialization would create a JSON-API resource object like:

    ```javascript
    {
      "data": {
        "type": "comments",
        "attributes": {
          "title": "Rails is unagi",
          "body": "Rails? Omakase? O_O",
        },
        "relationships": {
          "author": {
            "data": {
              "id": "12",
              "type": "users"
            }
          }
        }
      }
    }
    ```

    By default, attributes are passed through as-is, unless
    you specified an attribute type (`attr('date')`). If
    you specify a transform, the JavaScript value will be
    serialized when inserted into the attributes hash.

    Belongs-to relationships are converted into JSON-API
    resource identifier objects.

    ## IDs

    `serialize` takes an options hash with a single option:
    `includeId`. If this option is `true`, `serialize` will,
    by default include the ID in the JSON object it builds.

    The JSONAPIAdapter passes in `includeId: true` when serializing a record
    for `createRecord` or `updateRecord`.

    ## Customization

    Your server may expect data in a different format than the
    built-in serialization format.

    In that case, you can implement `serialize` yourself and
    return data formatted to match your API's expectations, or override
    the invoked adapter method and do the serialization in the adapter directly
    by using the provided snapshot.

    If your API's format differs greatly from the JSON:API spec, you should
    consider authoring your own adapter and serializer instead of extending
    this class.

    ```js [app/serializers/post.js]
    import JSONAPISerializer from '@warp-drive/legacy/serializer/json-api';

    export default class PostSerializer extends JSONAPISerializer {
      serialize(snapshot, options) {
        let json = {
          POST_TTL: snapshot.attr('title'),
          POST_BDY: snapshot.attr('body'),
          POST_CMS: snapshot.hasMany('comments', { ids: true })
        };

        if (options.includeId) {
          json.POST_ID_ = snapshot.id;
        }

        return json;
      }
    }
    ```

    ## Customizing an App-Wide Serializer

    If you want to define a serializer for your entire
    application, you'll probably want to use `eachAttribute`
    and `eachRelationship` on the record.

    ```js [app/serializers/application.js]
    import JSONAPISerializer from '@warp-drive/legacy/serializer/json-api';
    import { underscore, singularize } from '<app-name>/utils/string-utils';

    export default class ApplicationSerializer extends JSONAPISerializer {
      serialize(snapshot, options) {
        let json = {};

        snapshot.eachAttribute((name) => {
          json[serverAttributeName(name)] = snapshot.attr(name);
        });

        snapshot.eachRelationship((name, relationship) => {
          if (relationship.kind === 'hasMany') {
            json[serverHasManyName(name)] = snapshot.hasMany(name, { ids: true });
          }
        });

        if (options.includeId) {
          json.ID_ = snapshot.id;
        }

        return json;
      }
    }

    function serverAttributeName(attribute) {
      return underscore(attribute).toUpperCase();
    }

    function serverHasManyName(name) {
      return serverAttributeName(singularize(name)) + '_IDS';
    }
    ```

    This serializer will generate JSON that looks like this:

    ```javascript
    {
      "TITLE": "Rails is omakase",
      "BODY": "Yep. Omakase.",
      "COMMENT_IDS": [ "1", "2", "3" ]
    }
    ```

    ## Tweaking the Default Formatting

    If you just want to do some small tweaks on the default JSON:API formatted response,
    you can call `super.serialize` first and make the tweaks
    on the returned object.

    ```js [app/serializers/post.js]
    import JSONAPISerializer from '@warp-drive/legacy/serializer/json-api';

    export default class PostSerializer extends JSONAPISerializer {
      serialize(snapshot, options) {
        let json = super.serialize(...arguments);

        json.data.attributes.subject = json.data.attributes.title;
        delete json.data.attributes.title;

        return json;
      }
    }
    ```
